Description
본 발명은 운송수단의 좌석시트를 작동하기 위한 서보모터 내 유성기어로서, 부쉬가 미장착되고 코팅처리되어 마찰력 감소 및 내구성이 향상된 부쉬가 미장착된 코팅처리된 유성기어에 관한 것이다.The present invention relates to a planetary gear in which a bush is not mounted, and the bushing is not mounted and coated to improve frictional force and to improve durability, as a planetary gear in a servo motor for operating a seat seat of a vehicle.
차량의 운전자 및 탑승자가 앉는 시트에는, 대체로 탑승객이 수동으로 조작하여 시트를 상, 하방으로 이송시키도록 된 타입과, 전동기어에 의한 동력으로 자동 이송이 가능하도록 된 타입의 시트 이송장치가 설치되어 있다. Seats in which the driver and occupant of the vehicle sit are generally equipped with a seat transport device of a type that allows the passenger to manually transport the seats upward and downward, and a type that enables automatic transport by electric power by an electric gear. have.
이러한 시트 무비용 모터장치는 시트백 프레임과 쿠션프레임이 연접하는 부위에 설치되어, 시트백 프레임의 각도조절을 가능하게 하는 것으로, 상기 시트 무빙용 장치는 시트 착석자가 레버를 직접 조작하여 작동시키는 수동식과, 스위치 조작에 따른 전동모터의 힘으로 동작하는 전동식이 있다.The motor device for the seat movie is installed in a region where the seatback frame and the cushion frame are in contact with each other, so that the angle of the seatback frame can be adjusted. The seat moving device is a manual type in which the seat occupant operates the lever directly, and There is an electric type operated by the power of the electric motor according to the operation of the switch.
이 중, 전동모터를 이용하는 상기 전동식 서보모터의 경우, 전자기력에 의해 회전되는 아마츄어가 기어하우징에 내설되어 있고, 아마츄어에는 길이방향으로 회전축이 형성되어 있으며, 회전축 단부에는 회전력을 전달하기 위한 웜이 형성되고, 이러한 웜이 웜기어와 치합되어, 웜기어를 회전시키게 된다. 이러한 웜기어는 아마츄어의 웜이 형성되어 있는 부분에서 아마츄어와 십자형태로 교차되는 형태로 배치된 스핀들에 형성이 되는 것인데, 회전력을 전달받은 스핀들은 회전하면서 아마츄어와 교차되는 방향으로 전진 또는 후진하는 직선 추력으로 변환된다.이러한 스핀들의 일단은 차량의 시트와 동력전달가능하게 연결되어, 스핀들의 전, 후 움직임에 따라 시트를 전, 후 작동시키는 작동을 할 수 있게 되는 것이다.Among them, in the case of the electric servo motor using an electric motor, an armature rotated by electromagnetic force is built into the gear housing, and an armature is formed with a rotating shaft in the longitudinal direction, and a worm for transmitting rotational force is formed at the end of the rotating shaft. The worm meshes with the worm gear, thereby rotating the worm gear. The worm gear is formed on a spindle arranged in a cross shape crossing the armature in the part where the worm of the armature is formed, and the spindle that receives the rotational force rotates and the linear thrust moves forward or backward in the direction intersecting the armature. One end of the spindle is connected to the seat of the vehicle so as to be able to transmit power, so that it is possible to operate the seat forward and backward according to the front and rear movements of the spindle.
이러한 서보모터에서 전술된 웜기어에 의해 회전력을 전달받는 드라이브 휠 내의 구성 중, 웜기어와 동력전달가능하게 연결되는 유성기어의 경우, 기존에는 유성기어의 중앙홀에는, 마찰력을 줄이기 위한 부쉬를 반드시 삽입설치하여 고정하는 공정 및 구성이 추가되어만 했다.Among the components in the drive wheel that receives the rotational force by the worm gear described above in such a servo motor, in the case of a planetary gear that is movably connected to a worm gear, in the conventional hole of the planetary gear, a bush for reducing friction is necessarily inserted and installed. Therefore, the fixing process and configuration had to be added.
즉, 서보모터를 구성함에 있어서, 부쉬 및 부쉬를 유성기어에 조립하기 위한 공정이 반드시 필요했으며, 이러한 부쉬는 작동 중 내구성 저하로 유성기어와 분리되는 문제가 발생되는 문제가 있었다.That is, in constructing the servomotor, a process for assembling the bush and the bush to the planetary gear was absolutely necessary, and such a bushing had a problem of being separated from the planetary gear due to deterioration of durability during operation.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 운송수단의 좌석시트를 조정하기 위해 설치되는 서보모터에서, 상기 서보모터 내에 삽입되는 유성기어의 경우, 회전력이 절달되는 중앙의 홀 내주연에 별도의 부쉬를 삽입하지 않고, 사전에 코팅처리를 하여 사용함으로써, 마찰력을 줄여 내구성을 향상시킬 수 있음과 동시에, 기존에 사용하던 부쉬 및 부쉬와 유성기어의 조립공정을 생략하여 비용을 절감할 수 있도록 한 부쉬가 미장착된 코팅처리된 유성기어를 제공하는데 있다.The present invention has been devised to solve the above problems, and the object of the present invention is a servo motor installed to adjust a seat seat of a vehicle, in the case of a planetary gear inserted in the servo motor, the rotational force is reduced. Without inserting a separate bush into the inner periphery of the center hole, and using a coating process in advance, the frictional force can be reduced to improve the durability, and the assembly process of the existing bush, bush and planetary gear is omitted. Therefore, it is to provide a planetary gear with a bushing without coating so as to reduce costs.
